 Hello!

 Well skb recycling is "research" and should be used to challange to vm/slab
 people to start with... And I guess you will get objections about the extra 
 stats as well.

 I see you increased the RX-ring to 1024 pkts. 
 Did you really see any improvement with this?

 Also I would be interested if you have any numbers for recycling patch? 

 Jamal and I spent some days after OLS to test and tune but it wasn't to 
 promising at that time but it's reworked now.
 
 
 Cheers.
